The counter balance required was not much (less than 4 pounds), so I used some fishing lead weight, see link below. It comes in a coil that conveniently wraps around the end of the boom. A length of magic tape secured it to the boom. \n \nPS: The arrangement worked fine but I wasn't happy that the weight of the whole thing was now twice the weight of the antenna. \n \nLink fyi: https://www.walmart.com/ip/Bullet-Weights-Lead-Wire/52497626 \n \n73! \nUmesh \nk6vug \n \n \n \n On Friday, October 4, 2019, 4:02:49 PM PDT, Don KB2YSI via AMSAT-BB <[email protected]> wrote: \n \n I use a square wooden dowel on the back end of my Arrow that I clip my RX\nradio on to act as a counter balance.\n\nOn Fri, Oct 4, 2019, 18:44 Bob Hammond via AMSAT-BB <[email protected]>\nwrote:\n\n> Hasan, front to back on the EL so as to reduce the load on the motor and\n> gears.\n>\n> thanks,\n>\n> Bob\n>\n> On Fri, Oct 4, 2019 at 8:16 AM Hasan al-Basri <[email protected]>\n> wrote:\n>\n> > Bob,\n> > Are you talking Front to Back (EL) or Side to Side ?\n> >\n> > When I had clearance issues I had to mount my 2m yagi forward of its\n> > natural balance point.
